April 27, 2006 - The Pennsylvania Department of Health is releasing the following information in preparation for the beginning of the 2006 West Nile Virus season.   In 2005, the Centers for Disease Control and Prevention reported 2949 human cases and 116 deaths (as of February 14, 2006) of West Nile Virus in the United States.  In Pennsylvania, 25 human cases of West Nile Virus and two deaths (contributing factors) were reported to the Department of Health.  To date, the virus has been detected throughout the United States except in Alaska and Hawaii.  In Pennsylvania, 33 of the 67 counties had West Nile Virus detected either in birds, mosquito pools, sentinel chickens, horses or humans.  Some counties had positives in all surveillance areas.  Because these findings indicate ongoing and widening enzootic transmission, we need to be vigilant and prepared for the re-emergence of West Nile Virus as the adult mosquito season progresses.  As we enter a new mosquito season, Pennsylvania Department of Health wants to keep you apprised of our surveillance activities and how you can help the Commonwealth deal with th is emerging disease threat.

Questions you may have about the West Nile Virus

What is West Nile Virus?

West Nile virus is a mosquito-borne infection that can cause brain inflammation. The virus was previously only found in Africa, Eastern Europe and West Asia, but was detected in Pennsylvania for the first time in the year 2000. West Nile virus infection in people occurs primarily in the late summer or early fall. People can get infected from the bite of certain kinds of mosquitoes, such as the Northern house mosquito, that are infected with the virus. Mosquitoes get it when they bite or take a blood meal from birds infected with the West Nile virus. Those mosquitoes then transmit the virus to people, animals, and other birds when biting to take blood. You can reduce the number of mosquitoes around your home and neighborhood by reducing the amount of standing water available for mosquito breeding.

What are the symptoms of West Nile?

The incubation period of a West Nile virus infection in humans is usually 5 to 15 days.  Most people who are infected by the West Nile Virus either have no symptoms or mild illness such as fever, headache, or body ache, before fully recovering.  Some people may also experience a mild skin rash, or swollen lymph glands.  A more severe infection may be marked by a severe headache, high fever, stiff-neck, stupor, disorientation, coma, tremors, convulsions, muscle weakness, paralysis, and occasionally death.

Who is at greatest risk?

All residents of areas where virus activity has been identified are at risk of getting West Nile.  People over age 50 have the highest risk of severe illness because of their weakening immune system, although anyone with a compromised immune system is at risk.  All who died in 1999 and 2000 were over 68 years of age.

What is the Treatment for WNV?

There is no vaccine to protect people from the West Nile encephalitis virus, nor is there a specific treatment, medication, or cure.  However, the symptoms and complications of the disease can be treated.  Severe cases may call for hospitalization, intravenous (IV) fluids and nutrition, airway management, ventilatory support, and prevention of secondary infections such as pneumonia.

What can I do to reduce the spread of the West Nile Virus?

Help reduce the number of mosquitoes in areas outdoors where you work or play, by draining sources of standing water. In this way, you reduce the number of places mosquitoes can lay their eggs and breed.

Where can I get mosquito control products?

Most hardware and chain home stores carry products for the homeowner, such as mosquito dunks or larviciding granules to put in areas of standing water.  These contain the bacteria Bti or Bs that inhibit the growth of the mosquito larvae and are environmentally safe to use.
